He is just a school shooter with a harder target. These guys are unhinged. Shooting the President or presidential candidate isn’t something any sane person does. I doubt this guy had a coherent thought, let alone a political agenda.
Just my worthless opinion, shot in the dark
As in the case of many recent school shootings and attacks on Republicans he'll have a manifesto, notes, and or social media posts that indicate a mental state of victimhood, Leftist / socialist ideology and deep seated mental instability. He was probably under FBI suspicion and identified with radicalization. Could be wrong, but i'd bet on the obvious. I'd assess and conclude he acted alone and was on psych meds under a Doctors care.
Here's today's sampling of social media experts
"Trump set this all up and he did this for sympathy, this was MAGA"
"the FBI & DOJ set this up and did it along with the CIA"
"the counter sniper failed miserably and knew nothing about his job, he delayed intentionally to allow the guy to hit Trump"
"the Democrat party set this up and is in coordination with the shooter"
"the Secret Service failed by delaying extraction and intentionally exposed Trump to get him shot"
"the deep state did this all and executed it perfectly in coordination with local police"
the list goes on...
I think we are phucked as a nation, Thailand and Vietnam are nice places to live, pass me a beer...I gotta take up smoking dope
